Known Issues

Known issues are provided below.

1. The VCK5000 incorrectly reports 4 MAC addresses with the satellite controller (SC) firmware version 4.4.9 installed. Only the first two MAC addresses are valid.

   The following work-arounds are available:

   1. Ignore the last 2 MAC addresses as they are invalid.
   2. Upgrade to satellite controller firmware version 4.4.10 or later. Refer to section Installing the Deployment Software in the VCK5000 Hardware Installation Guide (UG1531) for steps to update the SC.
2. VCK5000 faceplate makes it difficult to connect standard micro-USB cable to the card during debugging. Recommend to use an elongated USB cable which can be found in the Alveo Accessories Page.
3. When in the active configuration (fan assembly attached), the VCK5000 fan speed will modulate over several seconds. This is observed with all firmware releases. The fan will continue to provide sufficient airflow and does not impact card functionality.
   1. Upgrade to satellite controller firmware version 4.4.16 or later. Refer to section Installing the Deployment Software for steps to update the satellite controller.
